SLAVE APPARATUS FOR POWER SUPPLY CONTROL AND POWER SUPPLY CONTROL SYSTEM IN CONTROL PANEL

摘要

PROBLEM TO BE SOLVED: To provide a slave apparatus for power supply control and a power supply control system, in a control panel for eliminating a host network, for realizing saving of wiring work and low cost, by detecting a fault of power source voltage only with a low-order networks.;SOLUTION: When a voltage drop in an AS-i communication cable 6 for communicating with a master apparatus 3, using a transmission signal in which a communication signal is superimposed on the communication power supply voltage supplied from the power supply 2 for AS-i communication and in a DC24V auxiliary power supply cable 7 which is used to supply an auxiliary power supply voltage from a DC24V auxiliary power supply 1, the slave apparatus 5 for power supply control cuts off as a system these communication lines or auxiliary power supply cable.;COPYRIGHT: (C)2002,JPO
